 Product Description

WiFi Temperature Data Logger Comark RF312DualPlus Supplied With Double Thermistor Air Probes

The RF312DualPlus WiFi Dual Channel Data Logger with High Accuracy ‘Plus’ Specification Thermistor Probes can measure two temperature points with a single unit.

The two probes can measure the environment in which they are situated e.g. one could measure a refrigerator and the other could measure a freezer. This high accuracy data logger is accurate to ±0.2°C* (-15°C to +80°C) / ±0.4°F (+5°F to +176°F). The unit comes with a bracket that can be used to mount the data logger on a wall or surface. The probes are connected to the Data Logger via a 160mm Y splitter cable which is provided.

*Using the supplied Penetration/Air Probe

Note: The Logger is supplied with two multipurpose test probes. This logger is compatible with the regular RFAXxxxJ probes with the following accuracy specifications ±0.3°C (0°C to +70°C) / ±0.6°F (+32°F to +158°F), please see list of compatible probes below.

Data is streamed wirelessly to either the Comark Cloud or a local PC. If the data logger temporarily loses connectivity with the network, it will log readings until the connection is re-established (max 30 days at 10 second sample interval).

The Comark Cloud Dashboard is your new online Home for your Loggers and provides easy access to the critical information regards your system, including; the status of your favourite devices at a glance, review recent device events, view data and clear alerts, quickly navigate to the detail on all your devices.

Simply log on to the Comark Cloud Dashboard via your PC, Tablet or Phone.

Setup your loggers quickly and easily with the free PC software, after which all configuration is handled from the Cloud. See the Downloads section, under the Support Tab.

Although the Diligence WiFi data loggers have an impressive range this can be increased by using WiFi extenders.

The RF312DualPlus WiFi Dual Channel Data Logger with two probes, is a low power device containing a rechargeable battery. When configured, the data logger can operate for up to six months*. The battery can be recharged via a standard +5V wall adapter RF320 (UK/US) or a USB port using the cable provided.

The LCD display includes several features including Max and Min readings and indicators for battery state, alarms, RF312 connection and signal strength.

*Battery Life and Power Supply
The product will arrive partly charged, but ideally you should charge it for 24 hours before use for optimum performance. The battery can be recharged (unit must be between 0°C to +40°C / +32°F to 104°F) via a PC, a USB +5V wall adapter RF320 (UK/US), or a portable USB battery pack using the USB lead provided. It can also be permanently powered by the RF320 USB wall adapter. Readings may be affected while the internal battery is being charged. However, once charged, continued connection of the charger will have no effect.

Battery life is dependent on: transmission period, WiFi encryption method, WiFi encryption key rotation frequency (determined by the router/access point), signal strength between router/access point and WiFi device, presence volume and type of WiFi traffic from other devices, sample rate and operating temperature.

For more information on Battery and WiFi Considerations please read our Product Information Bulletin for RF300.

Please contact us if you want more information on the battery life of RF300 Transmitters and how to maximise it.
